a GatewayClient for a shard index, if present

getShardCount

int getShardCount()

Return the current value of the shardCount parameter.

Returns:

the current shard count

multicast

Mono<Void> multicast(GatewayPayload<?> payload)

Parameters:

payload - a single outbound payload

Returns:

a Mono completing when the payload is sent

unicast

Mono<Void> unicast(ShardGatewayPayload<?> payload)

Send a single ShardGatewayPayload to a specific GatewayClient instance, given by the routing information in ShardGatewayPayload.getShardIndex() and returns a Mono that signals completion when it has been sent.

payload - a single outbound payload

Returns:

a Mono completing when the payload is sent

logout

Mono<Void> logout()

Instructs that on subscription this group should log out from Discord Gateway.
